In the context of the electricity production, the solar energy is appropriate and endless. At present the technologies of solar concentration are the one which present most possibilities for commercial use. Thus, it is necessary not only to design processes of conversion of energy, but it is also important to assure an availability of these equipment by the conception of fault detection and isolation (FDI) systems. To improve the behavior of the solar power plant, we use a model based on differential algebraic equations to describe variations of the solar radiation, ambient temperature, flow rate and temperature of fluid. These phenomena are highly nonlinear. Moreover, a large class of nonlinear systems can be well approximated by T-S fuzzy models. The diagnosis scheme is based on a fuzzy observer to estimate faults and faulty system states; a proportional (P) observer to estimate constant faults in then adopted. Using descriptor redundancy property, a solution is proposed in terms of linear matrix inequalities (LMI). The performance of the proposed approach is pointed out by focusing on a model of solar power plant through numerical results.

This paper investigates differences of parasitic inductances caused by DC bus bar patterns on printed circuit boards(PCB). The DC bus bar pattern on the PCB is limited depending on the layout of main circuits and the control circuits. Two patterns which are a laminated wiring pattern and a plane wiring pattern are compared in experiments and simulations. In this paper, it will be clarified that effects of the DC bus bars on PCBs such as a surge voltage of a switch in terms of the parasitic inductance depending on the circuits on PCBs. As a result, if the same parasitic inductance which is 20 nH, is realized between each wiring pattern at the same length, the plane wiring pattern requires over ten times of the pattern width compared with that of the laminated wiring pattern. Hence, the circuit size can be downsized when the laminated pattern is used. From the experimental results, the maximum surge voltage in the plane wiring pattern is larger than that in the laminated wiring pattern. In this case, the parasitic inductance value of the plane wiring pattern is three times that of the laminated wiring pattern. However, the surge voltage in the laminated pattern is reduced by 7% compared with the plane wiring pattern. As a consequence, the ratio of the surge voltage does not match that of the parasitic inductance. As a result, not only the parasitic inductance of the DC bus bar but also it is necessary to consider other parasitic inductances on PCBs such as parasitic inductances into input capacitors and the path between an upper MOSFET and a lower one and so on.

The growing number of consumers representing non-linear loads has led to an increase in the level of harmonics and poor power quality. It is not news to apply active power filtering (APF), but the drawback is the lower efficiency and complexity. The described here active power filter control system is simpler and more efficient. It is based on a relay current regulator and its converter uses the existing DC bus of the rectifier. The theoretical basis of the APF is described. A model of the proposed APF (with its suggested control system and the common DC link) is simulated in Matlab. The result of this simulation demonstrates that the level of the Total Harmonic Distortion (THD) of the input current is less than 3 %. The input current matches the phase of the input (mains) voltage: i.e. the consumption of reactive power from the grid is minimized. The simulation is confirmed by experimental study of the APF with Common DC Link. The corresponding results are provided.

This paper presents the use of new particle swarm optimization (PSO) technique for tuning the PID speed controller adaptively for permanent magnet synchronous machine (PMSM) drives. The new PSO algorithm minimizes the integral square error of speed response for a PMSM drives. This algorithm uses a modified cost function that includes information about position following and overshoot error of the step response. Simulation results show that the controller that is tuned with this new PSO algorithm is superior to the traditionally tuned one in such a way that it has a smaller torque ripple and a smaller speed reference tracking error. Moreover, considering nonlinear structure of the inverter, optimization through actual system takes long time. In order to shorten the optimization time, new method that simplifies the current loop is applied.

This paper presents detailed energy and network models for the intelligent control of a distributed system which also comprises power generation from renewables. The two models provide interactive energy monitoring, intelligent control and power demand balancing at home, block and neighbor level. Particularly, it is here described how the energy model works and also details of how it has been validated are here given. Moreover, it is shown how the energy model simulation results are transferred to the network simulation software SynerGEE, set up by GL Noble Denton Industrial Services Ltd (UK), in order to fully perform network simulations.

This paper presents a three-phase three-level neutral point clamped (NPC) inverter based single-stage grid-connected photovoltaic (PV) system with shunt active power filter (APF) functionality. The proposed system can perform both the maximum real power injection with the perturb and observe (P&O) maximum power point tracking (MPPT) algorithm from the PV panels into the grid and active power filtering to compensate the load current harmonics. Thus, the PV system operates more efficiently compared to the conventional PV systems and can be useful for power system applications. Control of the proposed system is based on synchronous reference frame control algorithm and hysteresis band current control technique. The effectiveness of the proposed system is demonstrated with Matlab/Simulink simulations and validated through dSPACE DS1103 real-time control platform based laboratory experimental results.

In this paper single-phase instantaneous reactive power (p-q) method and non-active current method have been compared. Reactive power and reactive current calculation using these methods have been considered here under distorted voltage and current waveforms. It has been shown that these two methods have some limitations for reactive power compensation. The p-q method with hysteresis current controller and non-active current theory with sinusoidal pulse width modulation (SPWM) controller have been analyzed in Matlab/Simulink. A prototype system has been designed using TMS320F2812 EzDSP in the laboratory and assessment based on simulation and experimental results is given for these methods in this paper.

The paper describes a vector fault tolerant control of squirrel cage induction machines (IM). The field oriented control (FOC) was combined to robust sliding mode control (SMC). This last is a technique to adjust feedback by previously defining a surface. The controlled state variables will be forced to move on this surface, then the behavior of the machine slides to the desired equilibrium point. We have taken the stator interturn fault, which is the most frequently encountered in practice. An analytical method for the modelling of this fault has been presented including space harmonics effect. This method is based on the calculation of the magnetic field distribution through the machine air-gap. The obtained model is less complicated to be implemented for condition monitoring or to validate fault tolerant control algorithms. Simulation results show, on the one hand that the proposed control scheme provides highperformance dynamic characteristics, and on the other hand the applicability and the tolerance of this control.

The induction machine in the operating mode of generator is a very valuable alternative to the synchronous machines. Especially in lower nominal power rating range, such solution can be more cost effective. Induction machine with a squirrel-cage rotor cannot generate a reactive power and even more it is a permanent consumer of the reactive power. In this paper, we strive to define theoretical limits of operation if the electronic source of reactive power is used.
